Yeah but have you tried those products on Stihl plastic tanks and covers specifically? Dave is right, Stihl's plastic is a proprietary compound which can be really hard to work with.

Don't knock it till you try it. If you have ever been to a 3 day heavy equipment auction where every thing looks freshly painted & its not.
You begain to realize they are smarter then you. It is called Dakota shine.
From heavy equipment decals on dozers , draglines & cranes with new looking decals that would be impossable to replace.
From plastic cabs & engine covers on RT manlifts & RT cranes.
I got into it by rebuilding the comonweath L1A1 FAL rifles, the British L1A1 newer verisons have a pebblegrain plastic stocks called marynal . One tough plastic, the shine made them look new & it is a permanent finish.

I have lost the first part of the 2 part process of the last sample I had.
So I cannot prove anything on STIHL parts, but it will be proved later.

I've worked on heavy equipment before and understand the processes involved in refinishing various types of plastic, rubber, vinyl, powder-coated parts, and old baked-on enamels. Mine and others' points were that the glass fiber-filled plastic used in Stihl applications is unlike most other types of plastics used in OPE. If there is a product, like possibly this Dakota Shine, that works well on Stihl plastic- I'll be first in line to buy it.
 
You'd be well on your way to a new saw with that much money!!!

Kinda pricey for me just to make my saws shiny again!!!:dizzy:

It is expensve no doubt, but I used a sample of two small bottles that cost 25.00 bucks that would do stocks for hundred rifle kits.Selling for 300.00 each

That small kit is some thing new, but well worth the money if you buy & sell a large amount of used saws as I do.
 
Just a thought - I've found Westley's Bleche White - whitewall cleaner - to do a great job on some plastics.


I tried it on my 210 didnt seem to do anything. only thing I have gotton to clean my really dirty 210 was purple power wheel cleaner. still got alot to do to it, my orange is really faded from sitting outside.

Where did you get the small $25 bottles of that Dakota Shine?

I had to call & beg on my knees all most.
They told me it is just a saleman sample that they had to special fill. You might call & see if you can get it now in smaller lots.

Here again I need to prove that it would be worthwhile. the way it works is it breaks down or softens the clean surface of the plastic & then rehardens into a new surface finish that is permanent.
After being around most of the STIHL products that use plastic, one thing I have noticed STIHL is not much different then any other plastic engine shrouds.
In this I am saying it fades in the sun, cracks & splits under pressure.
It is reinforced where needed but yet it is nothing special only it maintains a consistant color unlike Husqvarna plastics.
And there is no reason why Dakota Shine should not work.:greenchainsaw:
 
It might leave a coating, but as for breaking down nylon base materials, cleaning it and making it look better... I'm highly skeptical.


Jacob - you try it first.

A good clean and scrub of the orange plastic followed by almost any car wax makes them look great.

Holy ****, thats pricey. I'd much rather purchase another project saw.

How come the plastic cleaning threads don't get the same abuse as the chain cleaning or bar painting threads?

Just curious.

Ha ha LOL, cuze ya'll like your sawz to be purdy!!
 
Thanks for all the tips!:cheers: , several things to try, but it helpful knowing I'm not the only one that has had trouble with this.

I've cleaned up alot of bad/scratched areas with some minor sanding, just need to finish up with some finer grits and polish or wax and call it good.
 
+ 1 Sand

I am happy with mechanical sanding the whites.I used sander with a
triangular pad.....lets me get into most spots ....the bits i can't, i use
angled bits by hand....if i had to do all by hand i would not bother....start
with 240 on the deeper stain and scratches then up to 600-800 grit .Then seal
The hard bits are the nooks and crannies.
Will certainly get rid of the age yellow tint and scratches..........
comes up like new.
But as i said would not bother doing by hand only.
There are cheap angle pad sanders .....get one you can change the
triangle pad size.

p.s I tried a crap load of cleaners , bleaches and cutting compounds with
very marginal results.

All well & good but you need to consider that Dakota Shine only works on the surface & that nylon is a form of plastic.
We used short nylon strips as a way to make concrete stronger in critical areas.

OK!! DAkota Shine is sending me a smaller kit for $29.00, they are selling.

It is enough for a small John Deere tractor.

They are sticking to their guns saying it will work on most any thing.
